Abstract

Jerusalem artichoke (JA) is a promising crop, classified as a foodstuff (tubers), animal feed (feeds or silage), and an energy crop (for bioethanol production). This crop has several economic benefits including the production of inulin, fructose, and proteins, as well as raw materials for the chemical, pharmaceutical and food industries. The present review mainly focus on the anatomical structure of unstressed JA which has distinguished features for stems, leaves, stomata and trichomes. Anatomy of JA plant may support its responses to harsher conditions including the physiological and metabolic changes. Under stress conditions, JA may undergo some biochemical and anatomical adaptations to survive depending on the kind of stress, abiotic (e.g., drought, salinity, waterlogging, heat stress, etc.) and biotic (insects, microbes, herbivorous, etc.). Hence, due to the rare or may be nothing studies on anatomical structure of cultivated JA under stress, many futures studies are strongly required to reflect the real anatomicall situation of stressed JA plants.
